Hi out there,
What i like to know, is how could you know, that a sudoku-like number table is
a real sudoku with only ONE SINGLE solution?
The Solvers from the quiz (which I did not read) will surely find a solution.
But where did the sudokus themselves came from?
What about a sudoku-generator? Which leads to: How to proof a certain number
table has one and only one solution?
Maybe the solvers do that already? And if so, which one does?
Sorry for the memo-style onf the message. It just came to my mind and had to be
"not using Ruby is punishment enough"
